How can i change resource file that i use it in my project at runtime !
or
How to change Resource file Dynamically ?!

See the MSDN[^] pages on resource files.

how to have :
System.ComponentModel.ComponentResourceManager res = new ComponentResourceManager(typeof("<code>C:\Resource.resx</code>"));

Is it ok in .Net 3.5 to change a property within a foreach loop? Does it still run the risk of producing unpredictable results? Also, will the potential results be noticeable or might it cause some type of slow, inconspicuous but nonetheless catastrophic error.
For example:
foreach(Employee janitor in EmployeesWithPayIncrease)
{
janitor.Salary += 5000;
}
Thanks for any help or information you can provide.

It is fine to change a property; the only thing you can't do is change the loop variable or the list itself.
So
foreach(Employee janitor in EmployeesWithPayIncrease)
{
janitor.Salary += 5000;
}is fine, but
foreach(Employee janitor in EmployeesWithPayIncrease)
{
janitor = new Employee();
}or
foreach(Employee janitor in EmployeesWithPayIncrease)
{
EmployeesWithPayIncrease.Remove(janitor);
}are not, as it would mean it would compromise the enumeration.If Barbie is so popular, why do you have to buy her friends?

So can I! But I figure that if he is asking a basic (sensible, but basic) question like that, I didn't want to confuse him with custom comparisons, etc. I found it refreshing to be politely asked a sensible question  If Barbie is so popular, why do you have to buy her friends?

True
I can also think of ways to make the other two pieces* of code work without (changing them, of course)
But it's not like that's going to happen in the real world a lot either
edit *: well ok only the last one, unless I'm allowed to cheat

Thanks for the information. I appreciate the answer.
However, I am curious: how could you make the first piece of code fail? Also, my code will work without unintended consequences, right?

The setter of that property could be changing the collection in some way

Well that depends on what the property is doing..

You can't modify an object in a foreach loop like that. You have to loop differently (for, while, etc).45 ACP - because shooting twice is just silly

Yes you can - provided the property you modify does not alter the comparison, or add / remove items from the collection. Increasing the salary would not be a problem.  If Barbie is so popular, why do you have to buy her friends?

When a foreach is applied to a collection, C# will have the collection return an enumerator (I believe by calling a method, GetEnumerator). With the built in .Net types, those enumerators have logic in them that throw an exception if they detect that the list has been changed since the enumerator was created. They do this by taking a snaphot of the version number stored in the collection. Whenever a collection is modified, .Net increments this version number. And whenever an element is gotten from the enumerator, it checks it's version number against the collection it was created from.
The version number is only incremented for operations that change the structure of the list (reordering items, item removal, item additions, assigning items, and so on), not ones that change simple attributes of the list.
Also, most programmers are not aware that this version incrementing and checking must be done, so many custom collections will not throw an exception when the collection was modified in a foreach. For example, you could yourself create a custom collection that doesn't check if the collection was modified. Then no exception would be thrown when you modify the collection (add items, delete them, etc).
Whether or not modifying the collection during a foreach would cause an error (note that I didn't say "exception", I said "error") entirely depends on the collection.

I want to initialize the values of a multi dimension array. Instead of this:
string[,] arr = {{"charles","mary","moses"},{"erik","ann","grace"}};
I'd want to do this:
string[] class1 = new string[3];
string[] class2 = new string[3];
class1[0] = "charles";
class1[1] = "mary";
class1[2] = "moses";
class2[0] = "erik";
class2[1] = "ann";
class2[2] = "grace";
string[,] arr = {class1,class2};
This is not working. It gives the error:
Invalid rank specifier: expected ',' or ']'
In the last line. The reason is that i have the values for the multi dimension array in single dimension arrays. What can i do to load Multi-Dimension Values like the above from single dimension arrays?Wamuti: Any man can be an island, but islands to need water around them!

A multidimensional array is not an array of array's, it's a single array with funky indexing.
If you change the declaration of arr to string[][] you could do what you want, but then of course it has become a jagged array (which just happens to accidentally be rectangular) instead of a multidimensional array.
If you really want a multidimensional array you could manually copy the arrays to their proper rows

Hello,
I wanna know If i declare function with same name, in interface and base class. and inherit this with Drived class. and call this function with drived obj.What Does it throws an error or not?
If not how its differentiates which function to call?
and how to call both the function?
EG:
<br />
Public Interface Iface<br />
{<br />
Void Display();<br />
}<br />
<br />
Public Class Base<br />
{<br />
Public Void Display()<br />
{<br />
Console.Readline("This is Base Class Method");<br />
} <br />
}<br />
<br />
Public Class Derived : Base, Iface<br />
{<br />
Public Void Display()<br />
{<br />
Console.Readline("This is Interface Method");<br />
} <br />
}<br />
<br />
Main()<br />
{<br />
Derived Dobj = new Derived(); <br />
Dobj.Display();<br />
Console.Readline();<br />
}<br />
Which function is called?
|
|
|
|
|
The interface will be called, Derived.Display(). After you fix the copiler-errors, since C# is case-sensitive I are Troll 
|
|
|
|

And replace Console.Readline with Console.WriteLine!
Tch! The quality of code fragments is just getting worse and worse... If Barbie is so popular, why do you have to buy her friends?

Yeah, it's good to see a post with an actual piece of code in it I are Troll

Ignoring the various errors in your code, the derived class Display will be called. To access the base clase method, use "base.Display()".
Derived Dobj = new Derived();
Dobj.Display();
public interface Iface
{
void Display();
}
public class Base
{
public void Display()
{
Console.WriteLine("This is Base Class Method");
}
}
public class Derived : Base, Iface
{
public void Display()
{
base.Display();
Console.WriteLine("This is Interface Method");
}
}
I think you need to read up on Interfaces: there is no code associated with an "interface method". The method you define in the Derived class implements the Interface method requirements, but masks the Base class implemenation - you will in fact can an error message to that effect that can only be got rid off by declaring it as "public new void Display()"If Barbie is so popular, why do you have to buy her friends?

| By definition, a static constructor is fired only once when the class is loaded. An instance constructor on the other hand is fired each time the class is instantiated. Thanks
